' MEANS FOR GENERATING SOUND.

Application filed February 17, 1922. Serial No. 537,264. i

T 0 all whom t mag/'concern movable fromthe body Be it known that GEORGE H. PARSONS, a citizenA ofthe United States, and a resident of New tYorkcity, borough of Manhattan, in thecountyof NewYork and State of New York, has invented cert-aincnew and useful Improvements in Means for Generating Sound, of which the following is a speciiication. l v

This invention relates to a sound device 'for toys and the object thereof is to provide means for generating sound to imitate a babys voice. l The device is intended for` use with a doll, -inwhich it is` placed and which when moved -innacertain way causes the voice to be generatedA'and-say ma-ma. A. A further object of my invention is to provide means whereby the device may be adjusted".to g say the wordvma-ma slowly or quickly, that is, .to regulate the time interval between the syllables. Y Y

A further .obj ect is toprovide avconstruction in which all-the vmoving parts with the exception of the vibrating` reed are open to view and adjustment 'when the casing is opened,l no working parts being concealed withinthe bellows or resonating chamber, and therefore, easy of access to adjust or repair.

Referring to the drawings forming a part of this specification: .Figure l indicates a doll in which the device is used and showing its preferred location. t l

y `Figure 2 is a plan4 view of the construction located withinthe casing,rthe Ytop of which isremoved.

Figure is a longitudinal sectional View.

Figure l is a cross sectional view on line y`4-of Figure 3. i

A, kindicates adoll and B a casing' made of cardboard or other suitable material and havingzavcover portion B- that is easily reortion thereof and in 4which is locateda-t 1in cloth B2 which covers an opening B3 formed in the cover, to permit the Isound ywaves produced by the device to flow freely vfrom within the casing.

C, indicates a bellowsof theihinged type, th`e 'hinge being Vformed at C. The bottom plate C2. of the` bellows may be secured to `the casing B by screwsfD-D respectively, or in any othersu'itable manner. yli/lounted jon thetop plate C3 of the bellows is a base plate E of metal which is made suficiently heavy to serve the function of a weight to compress the air in the bellows in its closing action and force same through the sound producing reed F, which is mounted in a resonating chamber G which chamber is provided with an air inlet H from the bellows chamber H', and an outlet H2 to the casing. The resonating chamber may be made of cardboard or tin or other suitable cheap material and may be secured to the top plate C3 by screws I or in any other suitable way.

Extending vertically and secured to the sides of the casing B is a stamped form of metal J which extends across the casing and through slots J-J respectively formed therein, and the ends of which are bent downward on the outer side of the casing as illustrated at K-K respectively which serves to brace the casing while at the same time the metal form is held in proper position to support its limbs L-L respectively, which extend downward therefrom and extend under the end of the bottom plate C"t of the bellows and is firmly held thereby.

A slot M is formed in each of said limbs L through which extend pins N-N respectively which in turn carries slidable bars O-O respectively which are vertically adjustable relatively, and are held in their adj usted relation by the thumb screws or nuts P-P which connect with the pins N-N respectively.

These pins O-O are made of flexible yielding material, such as soft rubber or thin strips of celluloid, which can be easily bent by pressing down the projecting end but which will instantly resume its hori- Zontal position when the pressure is removed.V

One of said pins O may be m'ade more flexible and easier to bend than the other by being made of smaller diameter relatively or it may be shorter in length to serve the function hereinafter described. j

P indicates a stiff wire which carries a valve 1P which controls the opening H2 in the resonating chamber. The wire P is connected to a short cylinder Q,'which is mounted on a shaft Q, which in turn is held by two brackets B-R respectively and a spring S is connected to said cube 2 at'one end and to the plate E at itsopposite end. The end P2 of the wire P' projects beyond the limbs L l-L respectively and is adapted to contact with the flexible members O-O. A U shaped frame F is also connected to the plate E at its two extremities and its upper portion extends above the wire P and serves to limit the upward movements of the valve P relative to the opening H2 formed in the resonating chamber. A small vent opening indicated by V is located in the resonating chamber to permit air to escape therefrom during the period that the valve Pv closes the opening H2 sothat the reedF can continue to vibrate when this valve is closed.

The device operates as follows With the bellows closed as illustrated in Figure 3, the first operation isto turn the c asing B so that the cover side'B2 is below the bottom of the casing, when the bellows will be expanded by reason of the weighted plate E and parts mounted thereon, causing the parts to assume the positionillustrated in the dotted lines in Figure 3 in whichposi tion the end of the wire P2 will have reached a osition adjacent the top bar J and the bellows in `its opening movements will have become filled with air.

When the-casing is again turned to its normal position as illustrated in Figure 4, the'bellows will start to close and will be compressed by the weight E causing the air to flow from the bellows chamber H through the passages H and H to the vibratingreed 'F and causing Sameto vibrate to produce sound whichis amplilied by the resonating chamber Gr:

Inthe commencement of this operation, the bellows in its downward movements carries the end P2 of the wire in contact with the upper flexible member O, which first causes the valve P to close theopening H2 in the resonating chamber and as the bellows continues its closing movement, sound is emitted by the vibrating reed F' which escapes through tlie opening V to produce a slight murmuring note and as the bellows continues to descend the flexible member O is bent until the end P2 of the wire slips past, when instantly, the spring S` Vacts to lift the valve P', thus opening the passage H2 and the loud volume of sound is at once emitted causing the first syllable of the word ma-ma to be uttered and as the bellows furtherV closes the end P2 comes in contact withthe lower element O, which first closes the valve P- and'bends in the same manner as the upper one did but by reason of its greater length, the end P2 is retarded for 'a greater length of timein passing this' pin than in Ypassingthe upper one and, therefore, the Sound Asyllable of vthe word 'is' spolrenV in slowerlperiod of time. n Byreversing the length of thetwopins relatively, the reverse action in speaking'the word would be effected. Y,

By changing the relative distance between the two flexible members O--Ol respectively,

the period of time in which the word is uttered would be decreased and vice-versa, as will be readily understood. v

.Having thus described my invention, I claim as newzl. A sound generating device comprising a casing havin an air compressing device therein, a soun ing device operated thereby, a resonating chamber, a valve controlling the rate of flow from said resonating chamber and means' comprising a plurality `of resilient members ada ted to automatically close said valve, an vmeanssfor opening same in relatively quick time compared to the closing movement, when seid resilient members release said valve.
